in early 1983 with a gala at the building, to which several LPC officials were invited. On September 8, 1983, the Cartier Building at 651–653 Fifth Avenue and 4 East 52nd Street was added to the National Register of Historic Places (NRHP), along with the adjacent building at 647 Fifth Avenue. The buildings were cited as examples of residences in Midtown Manhattan that were later converted to commercial use. The houses were added to the NRHP as a single listing, the "Houses at 647, 651-53 Fifth Avenue and 4 East 52nd Street". In 1987, Cartier asked the building's owner Olympic Tower Associates for permission to renovate the building's interior.

In May 2012, real estate investment firm Crown Acquisitions took a 49.9 percent stake in the Olympic Tower properties, which included 647 Fifth Avenue, the Cartier Building, the Olympic Tower itself, and a fourth building at 10 East 52nd Street. The Cartier Building received another renovation in 2014, designed by Beyer Blinder Belle in conjunction with Thierry W. Despont. During the renovation, the Cartier store was temporarily at the General Motors Building. The renovation was completed in 2016, two and a half years after it started. Guy Trebay of The New York Times described the 2010s renovation as having turned the Cartier Building into a "thing of rational and distinctly Gallic beauty".
